Exhaust pipe of an air conditioner

ABSTRACT

The present invention discloses an exhaust pipe of an air conditioner. The air conditioner includes a condenser, a first pipe, an air duct and a second pipe. The condenser is located in the air conditioner, an end of the first pipe is close to the condenser, the other end is penetrated out of a side of the condenser, and an interior of the first pipe is provided with the second pipe. An end of the second pipe is connected with the air duct (the air duct is located in the air conditioner), and the other end is penetrated out of the first pipe. Therefore, when the air conditioner is running, hot air is sucked into the condenser through the first pipe and then the circulated hot air is sent out of a room from the second pipe through the air duct, such that indoor temperature can be reduced effectively.

BACKGROUND OF THE INVENTION

a) Field of the Invention

The present invention relates to an exhaust pipe of an air conditioner, and more particularly to an exhaust pipe of an air conditioner which is able to reduce indoor temperature effectively.

b) Description of the Prior Art

As time change and evolution of technologies, many necessary electronic products in people's lives have begun to be popularized. Nowadays, due to global warming, weather is often unstable and temperature changes between hot and cold frequently. In old times, when temperature is so high that people feel uncomfortable, electric fans will be used to reduce ambient temperature of a person. In terms of the electric fan, a heat dissipation effect is actually very limited. As a result, to reduce temperature in an entire space, a device which can effectively reduce temperature in an indoor space is developed and this device is called an air conditioner. The air conditioner is installed at an air outlet or a window in a room to provide cold air circulation in the room. However, this kind of air conditioner can be only fixed at one place and cannot move by itself. Therefore, to solve this issue, a movable air conditioner is developed too. This movable air conditioner is provided with wheels at a bottom and is divided into two kinds on a market. One is an air conditioner with a single exhaust pipe and the other is with two exhaust pipes. The single-pipe air conditioner is currently the most popular movable air conditioner. In this movable air conditioner, cold air in a room is sucked in to cool down a condenser, and then, hot air is expelled out of the room by the exhaust pipe. This movable air conditioner is easily installed and is operated very conveniently. Yet, the single-pipe air conditioner cannot completely cool down temperature in an indoor space and the cooling effect is only limited to an area in front of an air outlet. For the single-pipe air conditioner, as cold air in a room is sucked in and expelled out, cold air is blown out again. In this process, hot air enters into the room through a crevice of a door, and indoor temperature cannot be cooled down completely either. On the other hand, a double-pipe air conditioner uses a pipe to suck in outdoor hot air to cool down the condenser and the other pipe to expel hot air out of the room. By the aforementioned structures, indoor temperature can be reduced very effectively. Nevertheless, this double-pipe air conditioner is installed very inconveniently, very large, very heavy and disgraceful; therefore, very few people will use this kind of air conditioner.

Accordingly, how to solve the aforementioned issues and shortcomings of the prior art is to be researched and developed for improvement by the present inventor and related vendors.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an exhaust pipe of an air conditioner. The air conditioner includes a condenser, an air duct and a first pipe which is located close to a side of the condenser, with an air inlet being defined at an end of the first pipe far away from the condenser. An interior of the first pipe is provided with a second pipe, an end of which is connected with the air duct and the other end of which is penetrated out of the first pipe; whereas, the air duct is connected with the condenser. Furthermore, an exhaust outlet is defined at an end of the second pipe far away from the air duct, such that when the air conditioner is operating, hot air is sucked into the first pipe from the air inlet and then enters into the condenser through the first pipe to cool (release heat of) gaseous refrigerant at high pressure and high temperature as liquid refrigerant at high pressure and medium temperature, through a cooling medium (air or water), and finally is sent out after flowing from the condenser to the second pipe through the air duct. By the aforementioned technologies, the issues existing in the conventional single-pipe movable air conditioner that indoor temperature cannot be cooled down completely and a cooling effect is only limited to an area in front of the air outlet, as well as the issues existing in the conventional double-pipe movable air conditioner that the double-pipe air conditioner is installed very inconveniently, large in size, very heavy and disgraceful, can be solved, thereby achieving the practical progressiveness that indoor temperature can be reduced effectively by the exhaust pipe of an air conditioner of the present invention, which uses a design of the first pipe and the second pipe.

To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 and FIG. 2, it shows a first side view and a second side view of a preferred embodiment of the present invention. As shown in the drawings, an air conditioner 1 of the present invention comprises a condenser 11 which is provided in the air conditioner 1 to cool (or release heat of) gaseous refrigerant at high pressure and high temperature as liquid refrigerant at high pressure and medium temperature, through a cooling medium (air or water); a first pipe 12, an end of which is located close to the condenser 11, which is used as a necessary duct allowing outdoor hot air to enter into the air conditioner 1, and an end of which, far away from the condenser 11, is defined with an air inlet 121, with outdoor hot air being able to flow to the condenser 11 through the air inlet 121; an air duct 13 which is connected with the condenser 11, allowing hot air which is expelled out of the condenser 11 to flow outward; and a second pipe 14, which is provided in the first pipe 12, an end of which is connected with the air duct 13, the other end of which is penetrated out of the first pipe 12, and an end of which, far away from the air duct 13, is defined with an exhaust outlet 141, with hot air which is expelled out of the condenser 11 being able to be expelled out of a room through the exhaust outlet 141 and a side of the air conditioner 1 being provided with an air outlet 15 to blow out cold air.

Referring to FIGS. 3, 3A and 4 at a same time, it shows a first, second and third schematic view of an air direction of a preferred embodiment of the present invention. As shown in the drawings, the interior of the air conditioner 1 is primarily provided with the condenser 11, air duct 13, first pipe 12 and second pipe 14. The first pipe 12 is located close to a side of the condenser 11, outdoor hot air 2 can enter into the condenser 11 through the first pipe 12, and an end of the first pipe 12, far away from the condenser 11, is defined with the air inlet 121. In addition, the interior of the first pipe 12 is also provided with the second pipe 14 (pipe in a pipe), an end of the second pipe 14 is connected with the air duct 13 which is connected with the condenser 11, the other end of the second pipe 14 is penetrated out of the first pipe 12, and that end is defined with the exhaust outlet 141. Accordingly, when the air conditioner 1 is running, the outdoor hot air 2 will enter into the condenser 11 from the air inlet 121 of the first pipe 12 and then enter into the second pipe 14 from the condenser 11 through the air duct 13, after carrying out heat exchange in the air conditioner 1. Finally, the outdoor hot air 2 is expelled out of the room from the exhaust outlet 141. As a result, an extremely good effect of reducing indoor temperature can be achieved, not limited to an area in front of the air conditioner 1.

Accordingly, referring to all the drawings, the present invention is actually provided with following advantages when compared with the prior art:

-   -   1. The air conditioner 1 of the present invention utilizes a         design of the first pipe 12 and the second pipe 14 (pipe in a         pipe) to achieve an effect of enhancing reduction of indoor         temperature, such that there will be no shortcoming that         temperature cannot be reduced (not cold or only limited to an         area in front of the air outlet 15).     -   2. The size of the air conditioner 1 of the present invention is         equivalent to an ordinary single-pipe movable air conditioner;         therefore, it will not result in an issue of taking up too much         space (not like a double-pipe air conditioner with a large size         and a heavy weight).
